When the trunk latch no longer responds to its power controls, the Dorman trunk lock actuator motor, part number 937-866, is designed to take over the job of the original electric actuator that operates the trunk latch. It fits many BMW models, among them the 2007-2013 BMW 328i, 2008-2013 BMW M3 and 2006-2011 BMW 323i. See the "Vehicles it fits" section for the full list and engine details.
Dorman catalogs this unit as an integrated lock actuator for the trunk. It is built to match the original actuator motor's fit and function and is intended to bring back trunk latch operation where the factory actuator has failed. As a direct replacement, it plugs into the factory wiring.
- Ideal replacement: made to stand in for the original equipment actuator motor and help restore trunk latch functions.
- Simple installation: factory-style connectors plug into the original wiring harness.
- Cost-effective solution: provides original equipment function at a competitive price.
- Quality tested: Dorman puts this part through extensive testing for a quality fit and long service life.
Signs the trunk lock actuator may need replacing include a trunk that no longer releases from the interior button or key fob, a latch that locks or unlocks only intermittently, or no sound of the actuator working when the release is pressed. A fuse, switch or wiring fault can cause similar symptoms, so diagnose the circuit before replacing the actuator.
